{Help}Sql Query For uping numbers

[Corosive720]

Ok im in need of some help from the mmowned community. Me and My friend are going to merge Servers right.. But his accounts and chars when imported to mine will interfer with my and cause a error i know there is a way to do it.. So i was wondering What is the sql query that i would need to do to update his account id's and char index's so they dont interfer with mine? like so maybe like have the first one start at 6000 and go up by one for each account.

Thanks in advance for your help.. and please no useless posts like or this cant be done or such..

Some programs can do it for you.

You can however use php to achieve this
